In sports practice, cross-country ski athletes often incorporate maximum strength- or explosive strength training to their work-out routine. Hypertrophy training, especially in the upper body is generally recommended to be avoided, as increased bodyweight is thought to be detrimental for endurance performance. However, some authors indicated that peak oxygen uptake (VO2peak) is considerably influenced by the active muscle mass during exercise (Larsen et al., 2016). Therefore, it seems reasonable that upper-body hypertrophy could increase VO2peak in double poling (Wislof & Helgerud, 1998). However, various studies reported strong positive correlation between fat-free mass in the upper-body and DP performance (r= 0.69-0.92) (Osteras et al., 2016). The aim of the present pilot study was to compare the effects of two hypertrophy training regimes with high volume on sport-specific performance parameters in elite youth cross-county skiers and biathletes, one with high-load resistance and one with low-load resistance.
